Amazon Linux 2022 release notes update 2022-08-10
Major updates
This is an updated Release Candidate (RC) for Amazon Linux 2022 (AL2022), RC0.1.
An RC is a version that is nearly ready for release, but is still being tested. An RC receives only patches and bug fixes leading to the Amazon Linux 2022 Generally Available (GA) release. A GA distribution feature set is stable with no major changes expected between the final RC and the GA versions.
An RC version is not intended for production workloads. It's intended for testing purposes and to help you prepare for migration to Amazon Linux 2022.
Amazon Linux 2022 includes the following major updates.
-
This release represents the updated Release Candidate (RC0.1) for Amazon Linux 2022. You can use the Release Candidate to test compatibility with your applications or prepare for migration to Amazon Linux 2022.
-
In this release, we have removed the remaining
openjdk
packages, as we have shifted Amazon Linux 2022 to use Amazon Corretto as the JVM in the distribution.
Upcoming Changes in future Release Candidate AMIs and repos.
-
The legacy
pcre
package will be removed postRC0.1
and will be completely replaced by the more modernpcre2
package. -
The kernel package will see changes to improve aspects of security and performance, and, while core functionality will be maintained, some unused or deprecated features may be removed in future Release Candidates.
Java Ecosystem
-
The
maven
,xmvn
, andjavapackages-tools
should function as expected, but the versions present in this release have not yet been rebuilt after a bootstrap phase. These packages will be re-built without the use ofjavapackages-bootstrap
before General Availability.
Known Issues
-
All known issues are resolved.
Security Updates
-

Curation of packages - As part of the development cycle, we have curated the list of packages available in the repositories. This involved removing a number of packages that were no longer needed due to dependencies. Some package may be re-added to the repository as we work through customer requests.
-
Language run-times were updated and some runtimes like Ruby were name-spaced allowing newer versions to be added in the future without removing the current ones from the repositories.
